Addressing the 29th session of the Human Rights Council in Geneva on 15 June, High Commissioner for Human Rights Zeid Ra’ad Al Hussein called on representatives of “States with influence in the region to exert that influence, singly and collectively, to reverse the living nightmare that Syria has become for its people, and to encourage more constructive choices by all actors”. The UN Human Rights Chief particularly welcomed the recent call by the Russia Federation for accountability regarding allegations of use of barrel bombs filled with chlorine gas. “All sides must be held accountable for violations. There will never be sustainable peace where impunity prevails”, he noted.
